[Procedure] How to flush your DNS & reset your TCP/IP

Over time, your system will automatically collect and store IP addresses and other DNS results, in order to speed up subsequent requests it makes to the same hostname. This is perfectly fine, but at times, bad or corrupted results will also be cached and therefore require to be cleared from your cache in order to communicate with hosts correctly.

Similar to this, your TCP/IP settings may get corrupted, and will need to be reset. To perform this procedure, follow the steps found below.
